Fix MISRA rule 10.1 violations involving gk20a_nonstall_ops enums by replacing them with with corresponding #defines. Because these values can be used in expressions that require unsigned values (e.g. bitwise OR) we cannot use enums. The g->ce2.isr_nonstall() function was previously returning an int that was a combination of gk20a_nonstall_ops enum bits which led to the violations.
